SPECIFICATION forming part of Letters Patent No. 579,517, dated March 23, 1897.m

Application iiled December 11, 1895. Serial No. 571,804. (No model.)

.T0 all whom, it 71mm/ con/cern,.-

Be it known that I, ANDREW W. KNITTEL, a citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Wire Mats; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in mats, and relates more particularly to that class that are constructed of wire and are commonly known as doormats and the like.

The invention has for its object the construction of amat of the above-described class which will lie flat when on a smooth surface and not curl up at the edges, which is a serious objection with many of the wire mats now used.

A further object of the invention is the construction of a wire mat that can be folded and laid away when not in use, thereby taking up less space than the ordinary wire mats.

A still further obj ect of the invention is the construction of a mat of the above-described class that will be extremely simple in its con* struction, strong, durable, effectual in its operation, and comparatively inexpensive to` manufacture.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more specifically described, and particularly pointed out in the claim.

In describing the invention in detail refer ence is had to the accompanying drawing, forming a part of this specicatiomand wherein like letters of reference indicate similar parts throughout the view, which is a top 5 plan view of my improved mat.

In the drawing, I have shown a mat in three sections, and a a represent the spiral wires forming the body portion of the sections. The said wires are adapted to abut against each other and are secured rigidly by wires t b, forming retaining-stays. The sections are secured together by the spiral wire of one section being interwoven with the engaging wire of the other section, as shown at c c. The ends of the mat also have the spiral wires interwoven to form a strong end, as shown at d d. The ends of the spiral wires are secured to the retaining-stays b b, as shown at e e. By'this construction of a wire mat in sections it will be readilyapparent that the ends of the same, by reason of the interwoven spiral wires securing the sections together, will always lie flat, and the lspiral wires abutting closely against one another and retained in this p0- sition by the retaining-wires will present an even surface on the top of the inat.

The advantages of the folding mat aside from allowing the mat to lie fiat and not curl up will be readily apparent when used for street and railway cars and the like, as they can easily be folded up and laid away when not in use.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The wire mat consisting of a series of independent sections, witli the spiral wires forming the body portion thereof adapted to abut against each other and rigidly secured by stay-rods, the ends of said spiral wires being connected to saidstay-rods, said sections being secured together by the spiral wire of one section being interwoven with the corresponding wire of the opposite section, and said sections also having interwoven spiral-wire ends, all as shown land described.

In testimony whereof I affix my signature in presence of two witnesses.
